2. What is abstraction?

Explanation

Abstraction is the process of simplifying complex details to create a clearer mental model.

Submit
3. What is an algorithm?

Explanation

Algorithms are systematic approaches to problem-solving that involve clear, logical steps and a definite solution. They are not random, chaotic, or unsolvable.

Submit
4. What is Binary Search?

Explanation

Binary Search involves efficiently searching for an item in a sorted list by narrowing down the search area in each comparison, leading to a logarithmic time complexity.

Submit
5. What is a Concrete Step?

Explanation

A Concrete Step refers to any step in a process or procedure where the details are clearly defined and specified, making it easy to follow and execute.

Submit
6. What is a control structure in programming?

Explanation

Control structures in programming are statements or instructions that dictate the flow of control within a program, affecting the order in which other instructions are executed. They are essential for determining the logic and decision-making processes within a program.

Submit
7. What is data abstraction?

Explanation

Data abstraction involves hiding the complex implementation details and showing only the necessary features of data.

Submit
8. What is information hiding?

Explanation

Information hiding is a fundamental concept in software design, where the internal workings of a module are intentionally concealed to prevent unintended access and modification. This practice helps maintain the integrity of the module and increases security by limiting the exposure of sensitive details.

Submit
9. What is a nested structure in programming?

Explanation

A nested structure in programming refers to a situation where one control structure is placed inside another, allowing for finer control and logic flow. It is commonly used in languages like C, C++, and Python to handle more complex logic.

Submit
10. What is meant by Procedural Abstractions?

Explanation

Procedural abstractions involve separating the logical view of an action from how it is implemented, allowing for easier maintenance and understanding of code.

Submit
11. What is recursion?

Explanation

Recursion refers to the concept of a sub-program calling itself within its own code. It is a fundamental programming technique used for solving complex problems and is commonly used in algorithms and data structures.

Submit
12. What is a control structure?

Explanation

Control structures in programming are used to alter the flow of control in a program, determining the order in which instructions are executed. They are not related to data storage, web design languages, or hardware components.
